Alarm Correlation in Hybrid Networks
Measurement Point Services • TL1 MP Provide to execute the TL1 commands on ONS equipments. – • SNMPLite MP Get the status of specific router equipments. – • • Correlation MP Correlation MP Implement the alarm correlation algorithm that we proposed to simplifies root-cause – analysis.

Results • Codec • PacketLossRate • Bandwidth • Delay (ms) • Delay (ms) • Jitter (ms) • MOS – 5-point scale: Bad 、 poor 、 fair 、 good 、 excellent. 10/02/2010
Future Development • We are going to install perfSONAR-BUOY on all TWAREN GigaPOPs. We are going to integrate this alarm correlation system with our production • environment. • Based on perfSONAR framework, we will continue to develop management system for SDH or DWDM equipments.
Acknowledgement • The useful resources for development. perfSONAR Developer’s Wiki – perfSONAR Mailing List – • We also give thanks for Ikeda-san to help us to test the perfSONAR-VQM between Taiwan and Japan.
